Check Digit Verification of cas no

The CAS Registry Mumber 22488-76-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,4,8 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 22488-76:
(7*2)+(6*2)+(5*4)+(4*8)+(3*8)+(2*7)+(1*6)=122
122 % 10 = 2
So 22488-76-2 is a valid CAS Registry Number.

Synthesis of E-α,β-unsaturated ketones with complete stereoselectivity via sequential aldol-type/elimination reactions promoted by samarium diiodide or chromium dichloride

Concellón, José M.,Rodríguez-Solla, Humberto,Concellón, Carmen,Díaz, Pamela

, p. 837 - 840 (2007/10/03)

E-α,β-Unsaturated ketones can be obtained with complete E-selectivity by a sequential reaction of dichloroketones with a variety of aldehydes. This transformation was promoted by SmI2, SmI2 in the presence of FeCl3 or CrCl2. The best results were obtained when CrCl2 was used as the metallating agent. A mechanism based on a successive aldol-type reaction and a β-elimination is proposed to explain these results. Georg Thieme Verlag Stuttgart.
